Once Mighty

Panel 1: A world of warcraft landscape. There are baddies running around.
Narrator: Millions of heroes once kept Azeroth in check.
But no more.
It's now overrun by demons and monsters.
The once mighty Alliance and Horde have laid down their weapons.
But why?
Panel 2: Inn interior. A woman outside is grabbed by a baddie - a mogu. Inside is a blue-haired gnome and a panda, sitting at a table. They're playing a card games. There's a Hearthstone: heroes of Warcraft picture on the wall.
Victim lady (to gnome and panda inside): It's that damn card game!
